Charge transport in the glassy state of a variety of low molecular-weight organic compounds has ben studied. The hole drift mobility of the molecular glass was found to be of the order of 10-6 approximately 10-2 cm2V-1s-1 at an electric field of 1.0 by 105 Vcm-1 at room temperature, being higher than those of polymers and molecularly-doped polymer systems. The electric-field and temperature dependencies of charge- carrier drift mobility were analyzed in terms of the disorder formalism. The negative electric-field dependence of charge-carrier drift mobility was observed for the first time for the molecular glass. The relationship between molecular structure and charge-transport properties is discussed.
